1964 Map of Grable Coulee

USGS Topo · Published 1967

About this map

The Milk River flows across the southern reaches of this landscape, marking a vital water source for the surrounding prairie of Blaine County. This 1964 survey captures the agricultural and irrigation infrastructure essential to the region, including the Fort Belknap Canal and Harlem Canal. These waterways, alongside Thirtymile Reservoir, illustrate the systematic management of the river basin's resources during the mid-20th century. The northern portion of the Fort Belknap Indian Res is visible here, showing the intersection of tribal land with the expanding regional transport network.
